http連接錯誤javax.net.ssl.SSLPeerUnverifiedException：沒有對等證書

在下面的代碼中，我正在做的是從Web服務獲取微調項目。並在項目選擇，一些過程完成。問題是它沒有從服務器獲取數據到微調器。http連接錯誤javax.net.ssl.SSLPeerUnverifiedException：沒有對等證書

Frnt_mapActivty1.java

/*****************************FOR LOCATION FOR**************************************/ 
//Download JSON file AsyncTask 
public class LocationList extends AsyncTask<Void, Void, Void> { 
    JSONObject jsonobject; 
    JSONArray jsonarray;

e.getMessage（）返回空消息 –

我有什麼可以用e.getMessage的'代替（）'。 – priya

@priya看到我的回答 –

引起：顯示java.lang.NullPointerException：在的println需要android.util.Log.println_native消息（Native Method）

問題

Log.e("Error", e.getMessage());

e.getMessage（）爲null

拋出NullPointerException當應用程序試圖使用具有空值的對象引用

檢查

e.getMessage（）== NULL

嘗試用

if(e.getMessage()==null) 
{ 
    Log.e("Error", " "+e.getMessage()); 
    e.printStackTrace(); 
} 
else 
{ 
    Log.e("Error", e.getMessage()); 
    e.printStackTrace(); 
}

讀NullPointerException : println needs a message in android
